package feign.jaxb;
Encodes requests using JAXB.

Basic example with with Feign.Builder:

 JAXBContextFactory jaxbFactory = new JAXBContextFactory.Builder()
      .withMarshallerSchemaLocation("http://apihost http://apihost/schema.xsd")

 api = Feign.builder()
            .encoder(new JAXBEncoder(jaxbFactory))
            .target(MyApi.class, "http://api");

The JAXBContextFactory should be reused across requests as it caches the created JAXB contexts.

public class JAXBEncoder implements Encoder {
  public JAXBEncoder(JAXBContextFactory jaxbContextFactory) {
    this. = jaxbContextFactory;
  public void encode(Object objectType bodyTypeRequestTemplate template) {
    if (!(bodyType instanceof Class)) {
      throw new UnsupportedOperationException(
          "JAXB only supports encoding raw types. Found " + bodyType);
    try {
      Marshaller marshaller = .createMarshaller((ClassbodyType);
      StringWriter stringWriter = new StringWriter();
    } catch (JAXBException e) {
      throw new EncodeException(e.toString(), e);
